    Study Notes

    Management Information Systems

    • Data and insights are essential assets in the digital age.
    • Management Information Systems (MIS) involve people, procedures, software, databases, and devices to provide information for decision-making.
    • The Fourth Industrial Revolution is fueled by data explosion, increased storage capacity, and increasing computing power.
    • Sensors collect data about users, activities, and environments.
    • Computing speeds have drastically increased from 5,000 instructions per second to 25 billion instructions per second.
    • Smartphones contain various sensors, including cameras, pedometers, light sensors, thermometers, fingerprint sensors, microphones, gyroscopes, accelerometers, magnetometers, and proximity sensors.

    Netflix vs Blockbuster

    • Blockbuster was a membership-based movie rental company with physical stores, requiring in-store browsing and physical disk borrowing.
    • Netflix transitioned from a mail-order DVD rental service to a streaming platform, offering a subscription-based model for accessing movies online.

    First-Mover Advantage

    • First-mover advantage refers to the competitive benefit gained by entering a new market first.
    • It allows companies to establish brand recognition, customer loyalty, market share, and secure resources.
    • This advantage is not guaranteed, as fast followers can learn from first-movers and iterate on strategies.

    Power of the Long Tail

    • The "Power of the Long Tail" concept emphasizes selling numerous niche products with low demand instead of focusing on a few bestsellers.
    • This strategy thrives on internet platforms that enable reaching niche audiences with specific tastes.

    Databases

    • Databases are organized collections of data, stored and accessed electronically.
    • Database management systems (DBMS) are software used to manage databases.
    • Database programmers or administrators manage databases.

    Types of Databases

    • Document Databases: Hierarchical data organization.
    • Relational Databases: Connected tables using key columns for relationships.
    • Analytical Databases: Multidimensional arrays, complex to manage due to large amounts of data.
    • Graph Databases: Utilize nodes and edges to represent data points and connections.
    • Key-Value Databases: Stored in dictionaries for fast look-up operations.
    • Column-Family Databases: Stored in schema-free columns, offering flexibility and suitability for unstructured data.

    Relational Databases

    • Most popular type of database, consisting of interconnected tables.

    Schema, Table, Column, Row, Key

    • Schema: Blueprint of data organization and relationships.
    • Table: Individual file or array of data.
    • Column: Field defining data types within a table.
    • Row: Record of a single instance.
    • Key: Field connecting or relating databases.

    SQL (Structured Query Language)

    • The standard language for creating and manipulating relational databases.
    • Used for simple query operations using "Select," "From," and "Where" clauses.

    Data Warehouses and Data Marts

    • Data warehouses are sets of databases designed for decision support.
    • Data marts are databases focusing on specific problem areas.
    • Data warehouses and marts mitigate the performance impact of running analytics on production databases.

    Production vs. Staging Databases

    • Production database: The actual output, reflecting real-time changes.
    • Staging database: A simulation for testing and editing changes before deploying them to the production environment.

    Data Considerations

    • Data Relevance: Ensuring data aligns with current and future goals.
    • Data Sourcing: Assessing data availability, cleanliness, completeness, accuracy, and value.
    • Data Quantity: Determining the appropriate amount of data needed.
    • Fairness: Mitigating discrimination by addressing bias in AI systems.
    • Misuse: Implementing security measures to reduce risks.
    • Privacy: Protecting personal information and addressing surveillance concerns.
    • Security: Safeguarding data and systems, incorporating regulations across domains.
    • Equity: Ensuring accessibility and inclusion for all.
